WPA key problem after installing XP SP1
Hi,
After upgrading the Win XP Professional with its SP1, I got at every logon a warning popup message "The license key that was used to install WinXP is not the same as the one used by SP1. Please, contact your supplier for the correct key." But even if I have the correct key, how to repair this, because there is no option "Windows Activation" in the Start menus ?
Thanks for any information.
